5
Grounding
In order to prevent the accumulation of electrostatic charges
which could generate an electric arc in a flammable or explosive
environment, it is necessary that all conductive components of the
system are grounded.
The gun must be ‘grounded’ via the fluid hose or the air hose.
The equipment to be painted must also be ‘grounded’ by means of
clamps fitted with cables or, if suspended, by means of hooks which
must be kept clean at all times.
Follow the shutdown procedure and always depressurize air and fluid
circuits before carrying out any servicing on the gun (cleaning
checking, maintenance of the fluid or cleaning of the gun nozzles).
This gun is a precision tool. Its proper operation requires frequent and
careful maintenance.
If it is carried out immediately after work, cleaning is easier and quicker.
Never use wire brushes, files or pliers for disassembly.
Before cleaning or disassembling any component of the equipment, it is
imperative:
- to stop the pump by cutting off the compressed air supply,
- to decompress the hoses by pulling the trigger.
Never store more than necessary inflammable materials inside the
working area.
These materials must be stored in approved drums and grounded.
Use only grounded metals containers for cleaning solvents.
Cardboard and paper are prohibited.
The tanks of fluids and cleaners must be grounded via a grounding
cable, either by means of clamps or some other means of attachment.
The parts to be painted are hung or placed by means of hooks or
supports which are grounded and kept clean at all times, in order to
always guarantee good conductivity to ground.
All insulation (cardboard, paper, plastic materials) must be kept to a
minimum in the work area.
The ground continuity must be checked by a qualified technician.
Never operate the equipment without ensuring that all the above
safety requirements are met.
6
Pressure
The use of pressurized air and fluids (paints or solvents) presents
risks for the user and the equipment.
Never exceed the maximum working pressures of the equipment,
components and accessories.
For all cleaning, inspection and maintenance operations on the
equipment, it is imperative to follow the procedures for decompression,
shutdown, locking of any residual pressure, elimination of residual static
electricity charges and purging of fluids
Surfaces,

7 Storage
Our equipment must be stored in its original packaging.
In case of prolonged storage, it is preferable to carry out preventive maintenance for all
lubricants before start-up.
Storage before installation
Storage ambient temperature 0 / +50 °C (32° F / 122° F).
Protect the complete unit from dust/dirt, water/condensation, moisture, vibration
and shock.
Do not remove the packaging until just before assembly.
Storage after installation
Protect the unit from dust/dirt, water/condensation, moisture and shock.
8 Start-up
Assemble the aircap on the gun by positioning it according to the desired spray
orientation.
Open at the maximum the air needles.
Open the fluid needle as far as i twill go without a stop.
Connect the air hose.
Assemble the cup or connect the fluid hose.
Pull the trigger and check that the air is circulating normally.
9 Adjustments
This professional spray gun features 3 controls :
Spraying fineness
Air is fed by the central air. The air is adjusted by means of the air regulator
mounted upstream of the gun on the network and more precisely by means of
the knob at the bottom of the gun handle on some manual guns.
Fan width
Fan width is adjusted by using the knurled knob. It controls the air going to the
horns on the aircap. In this way, the air is controlled through the fanned air outlets
and allows the fan to change from flat (wide open) to round (closed).
Fluid output
Having selected the proper fluid nozzle / needle assembly and the fluid pressure,
it is possible to:
Further control the output by changing the travel of the needle (using the needle
stop knob).
Optimal set up is usually obtained when the fluid needle is completely open.
When this needle is nearly closed, a constant flow of fluid cannot be
guaranteed.
14
10 Gun handling
When assembling the aircap on the gun, hold it vertically in order to correctly align the
aircap before screwing the aircap ring.
Proper position
Improper position
Keep the gun perpendicular to the surface to be painted.
Avoid working with the wrist.
Do not forget that crossed sweeps cannot correct irregularities. Spraying from a
stationary gun will not give you even coverage.
Start the pass and trigger just before the leading edge. Release the trigger
before the pass ends, just after the trailing edge of the object.
Make sure that overlapping from the passes is even.
15
11 Maintenance
11.1 Preventive maintenance
Daily
Check groundings.
Clean the outside of the spray nozzle with a soft brush and solvent.
Flush the spray gun.
When the spraying system will not be used for an extended period of time, take
off the nozzle and immerse it in s solvent filled container.
Weekly
Check leakage from the fittings
Monthly
Check hoses.
Operate the valves.
Remove the air valve, clean it if necessary. Grease it as well as the spring before
assembling.
Remove the needle as well as the rear line and the complete air valve.
Clean the parts and grease them before assembling.
Annual
Change the air valve. Grease the air valve as well as the spring, before
assembling.
Remove the gun.
Clean the parts.
Change the seals and any defective parts.
Grease them before assembling (refer to seal and servicing kits).
Note: Frequencies are given as an estimate. They must be adapted by the
maintenance service of the user for every installation depending on the fluid, the
workload and the working pressure.
12 Assembly - Disassembly
Before removing a component of the gun, some precautions have to be taken:
Shut off the fluid pressure,
Empty out the paint inside the cup or the receiver and clean it,
Fill the cup or the receiver with cleaning solvent,
Take off the gun spraying air cap,
Shut off the gun supply air pressure,
Adjust fluid pressure to 0.5 bar / 7.25 psi and let the solvent circulate,
Shut off the fluid pressure,
Remove the part to be cleaned or changed.
Before reassembling the different components, some precautions must be taken:
Clean all the parts with the appropriate cleaning solvent and a brush.
Install new seals if it is necessary after having lubricated them with PTFE grease.
Install new parts if it is necessary.
16
13 Assembly errors
The use of improper replacement or defective parts may result in hazards to personnel,
damage, malfunction or general shutdown of the equipment.
14 Troubleshooting
Distorted
spray
Slightly unscrew the aircap retaining ring and rotate the
aircap by one half turn. If the defect is reversed, one of the
lateral air holes is plugged up or deformed. Clean the gun
aircap with solvent and unclog the air holes with
compressed air. If the problem is not resolved, it means that
the fluid nozzle is damaged.
Displaced
spray
This comes from a defect in the central fan. Clean the
aircap and the fluid nozzle. Make sure that:
the aircap is correctly centered on the nozzle,
the nozzle is not too big for the needle,
When work is done with a large needle opening and the
needle almost closed, the spray pattern is not even in all
directions.
Fragmented
pattern
The fan air pressure is too high at the holes in the air cap
horns:
turn the fan air
control clockwise to reduce the fan air
pressure,
increase the paint output.
Fan too thick
in the center
This is the reverse of the above defect:
the paint output is too high for the selected air pressure :
increase the spraying air pressure and reduce
the paint
output.
if the paint is too thick, dilute it.
Intermittent
spray pattern
An air inlet in the paint circuit creates an intermittent
pattern when:
the paint cup is nearly empty,
when the nozzle is not tightened on its seat: clamp it.
If the problem persists, remove the nozzle and clean it.
Check that the seat and the cone are not damaged,
remove the nozzle and clamp it.
Check that: the cup cover air hole is not blocked and the
paint is homogeneous and fluid enough (use the viscosity
cup).
Check that the ‘pressure’ gun is not being used with a
‘suction’ cup.
17
Trouble Cause Solution
No fluid out of the gun Clogged nozzle
Cut the pressure on
the pump.
Depressurize the hoses.
Remove and clean
the nozzle with solvent
by means of the brush.
Check the seal
condition.
Pattern width narrows
during reversing phase of
the pump
Air trapped in the fluid
circuit
Check connections

Tighten it.
Fluid leak at the packing Packing is worn
Tighten up the packing
holder without
blocking the needle.
If there is still a leak,
replace the packing
and the needle.
Fluid leak at the front part
of the gun, trigger released
Impurities in the paint Trigger the gun 3 or 4
times.
Needle worn or/and
nozzle worn
Replace needle
or/and nozzle.
